Title: Nonlocal non-Abelian gauge theory: Conformal invariance and β -function

Journal Article · · Physical Review D

This paper focuses on extending our previous discussion of an Abelian U(1) gauge theory involving infinite derivatives to a non-Abelian SU(N) case. The renormalization group equation (RGEs) of the SU(N) gauge coupling is calculated and shown to reproduce the local theory β-function in the limit of the nonlocal scale M → ∞ . Interestingly, the gauge coupling stops its running beyond the scale M, approaching an asymptotically conformal theory.
